Something went wrong((
1 - Downloaded
https://releases.broked.net/Z9Mini_2.3.tar.gz2 - in formatted 8GB FAT32 SD card.
3 - extracted from Z9Mini_2.3.tar.gz map files (md5_info, runme.sh, uramdisk.image.gz).
4 - disabled ASIC.
5 - inserted the card.
6 - enabled ASIC.
7 - and here the trouble, it took 5 minutes indicators do not go out((.
That is not what the instructions say. You only need to use SD card if you have signature checking enabled. And the SD card installation image starts with sd in the name.
For mini, just use the upgrade page and upload the image as is... no need to extract anything.
